I’ve overseen the installation of two Mitsubishi 9900-series UPS systems. In the US, Mitsubishi Electric Power Products, Inc (MEPPI) sells the systems. I believe that in other parts of the world, Toshiba sells the same UPS systems as the G9000-series through their TMEIC joint venture with Mitsubishi. We use the optional external “NetCom 2” SNMP modules to monitor the MEPPI UPS systems using our internal management systems. Finding the correct MIB to use proved to be a challenge!<\/p>\n
If you were lucky enough to snag a copy of Netcom_MIBs.zip<\/a> from MEPPI’s website before they took it down<\/a>, you could find a working MIB. Kinda. It didn\u2019t seem to work with Debian\u2019s net-snmp package. You could check the CD that comes with the NetCom 2, but at least in the two CD revisions I\u2019ve seen, there is no copy of the MIB file. Rather, they just tack it on as a 22-page appendix in their PDF documentation. Don\u2019t bother trying to copy\/paste a MIB based on the PDF, because it\u2019s the same, flawed definition found in the Netcom_MIB\u2019s.zip file.<\/p>\n The third place I looked was a mysterious CD (ISO name \u201cMitsubishi100\u201d). I say \u201cmysterious\u201d because they don\u2019t seem to ship it with all NetCom 2 modules. I got lucky, in that the second UPS we installed came with this CD. This disc contains a ups.mib file that actually works! My only complaint about it is that first line is \u201cUPS-MIB DEFINITIONS ::= BEGIN\u201d. The \u201cUPS-MIB\u201d definition collides with the standard IETF upsMIB namespace, meaning you can\u2019t use the same NMS to load both the Mitsubishi MIB, and the IETF MIB. The fix is easy\u2026 I just changed the definition to \u201cMEPPI-UPS-MIB\u201d instead.<\/p>\n I\u2019m including the file here, in the hopes that nobody else will have to retrace these steps to get a working MIB definition for their MEPPI NetCom 2 module.<\/p>\n MEPPI-UPS-MIB<\/a><\/a><\/p>\n","protected":false},"excerpt":{"rendered":" I’ve overseen the installation of two Mitsubishi 9900-series UPS systems.

\nIf you following the link<\/a> on the product’s web page<\/a>, you get an old, outdated copy of the IETF standard UPS-MIB. That’s no good, as the NetCom 2 does not use the standard upsMIB definition (.1.3.6.1.2.1.33). Rather, it’s under the enterprise number assignment<\/a> for “The Advantage Group” (.1.3.6.1.4.1.13891). (The NetCom 2 module itself is made by Unite Technologies — perhaps they are related entities?)<\/p>\n
